How about... FREE gun disassembly walkthroughs

On your computer, in 3D.

Totally Free.

Install the "Steam" app (free) and then install the game (also free).

It walks you through the strip, then makes you remember the re-assembly.

You can do field strip to full armorer's breakdown of 179 different firearms from the 1805 Harper's Ferry pistol to the 2015 Ruger Precision Rifle.

Sadly, only one Lever - the 1873 Winchester.

The "game" aspect of it is that you unlock later/more complicated guns by tearing down and assembling earlier/simpler guns.

Still, really cool.

Kinda reminds me of my 3rd year final exams at TSJC gun smith school.
The final exam was you draw 2 guns from a hat, 1 you disassemble completely and pass to someone else to reassemble. In return you got a box of parts to reassemble.
I dont remember what I took apart but I got the Remington 3200 to reassemble, all 140 odd parts. But here's the kicker, I had a pair of 3200's that I had rebuilt the previous summer so I knew them inside & out!
